| 摘要 |
The present invention relates to a secondary battery including multiple electrode assemblies and, more particularly, to a secondary battery comprising: a first electrode assembly having a first cathode, a first separation membrane, and a first anode; and a second electrode assembly having a second cathode, a second separation membrane, and a second anode, wherein the cross section thickness of the second electrode assembly is greater than the cross section thickness of the first electrode assembly when an area of an electrode plate for the second electrode assembly is smaller than an area of an electrode plate for the first electrode assembly. |
